Circuit operation principle is as shown in Figure 2: when LED group H is opened a way, and discharge tube T starts electric discharge, and discharge electric field is through two
It is input to the control pole of unidirectional thyristor Q2 after pole pipe D3 and resistance R6, makes unidirectional thyristor Q2 obtain and trigger signal and turn on,
Making oscillating circuit failure of oscillation, reach the purpose of protection, inductance L3 provides an about 10V to the negative electrode of unidirectional thyristor Q2 at ordinary times
Negative pressure, when load open circuit, negative pressure raises suddenly, accelerate unidirectional thyristor Q2 conducting, the effect of diode D2 is at list
When IGCT Q2 turns on, make the base stage simultaneously ground connection of audion VT2, accelerate audion VT2 cut-off, make protection fast and also can
Lean on.Owing to unidirectional thyristor Q2 control pole is at ordinary times without running voltage, so avoiding protection by mistake, enhance capacity of resisting disturbance.Often
Closing temperature switch S1 for overcurrent protection, its operating temperature selects to be advisable at 65～70 degrees Celsius, and by it against audion VT1
Or audion VT2 installs.Open circuit when part light fixture damages in access loads the heaviest or work process, overvoltage protection does not acts as
With, but audion VT1 and audion VT2 generates heat because crossing stream.When temperature is increased to set the limit, S1 opens a way, and circuit stops
Only work, protects the unlikely damage of power tube, and discharge tube T do not discharges time flat, when running into light fixture open circuit, transformer secondary output end N2 voltage
Suddenly raise, then discharge tube T starts electric discharge, protects power circuit and is not burned out.LED power circuit of the present invention can not only have
The function completing Power convert of effect, provides regulated power to LED lamp, and adds open circuit and current foldback circuit, when
When occurring light fixture open circuit and over-current phenomenon avoidance in circuit, it is possible to interrupting power circuit in time, protection power supply is not burned, and circuit is abandoned
Complicated chip structure, uses the combination of basic device, not only reduces cost of manufacture, and significantly increase circuit
Anti-interference so that it is normally can work in the environment of having electromagnetic interference, adds the range of circuit, therefore circuit
Have simple in construction, strong interference immunity, cost of manufacture is low, range is wide and open circuit, the advantage of overcurrent protection.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter
From the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only wraps
Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should
Description can also be formed those skilled in the art through appropriately combined as an entirety, the technical scheme in each embodiment
